In what context was the IREM Sterocomp voltage dip compensator used?
The commissioning of an IREM Sterocomp voltage dip compensator was recently completed successfully. The unit was installed to supply power to the lighting approach system of a Portuguese airport.
With this application, IREM confirms its position as a reference company in the Power Quality sector, expanding the range of IREM Sterocomp voltage dip compensators designed to ensure continuity and stability of electrical power supply in particularly critical environments.
What are voltage dips and why do they pose a risk to electrical systems?
Voltage dips are abnormal and unpredictable events that appear as a temporary reduction of the network voltage level below its nominal value. They generally originate from transient faults or the insertion of loads characterized by high inrush current. Their duration can range from ten milliseconds to one minute, but even a single short event can cause malfunctions or damage to electronic devices, particularly in modern systems where component sensitivity is high.
What advantages does the IREM Sterocomp voltage dip compensator offer?
The IREM Sterocomp voltage dip compensator is a solution designed to provide continuous protection against the most common disturbances occurring in modern electrical networks. It has been specifically developed for industrial applications with loads requiring high inrush currents or featuring regenerative braking.
A distinctive feature of this system is the absence of batteries: the additional energy required to generate the corrective voltage is drawn directly from the electrical network, ensuring simpler management and greater long-term reliability. The integration of a redundant internal bypass guarantees that the load continues to be powered even during system intervention, while its compact design allows easy installation within existing technical rooms.
For which applications is IREM Sterocomp suitable?
IREM Sterocomp has been developed to protect sensitive loads and to reduce economic losses caused by voltage dips, under-voltages, over-voltages, amplitude variations, or voltage asymmetries. It also provides protection against overvoltages of atmospheric origin.
Its applications are numerous and cover all industrial and tertiary sectors where it is essential to prevent production interruptions, direct damage to equipment, or loss of services, raw materials, and semi-finished products.

What is the range of IREM Sterocomp models available?
IREM Sterocomp voltage dip compensators are available in power ratings ranging from 300 kVA to 1800 kVA, expandable through the use of multiple synchronized units in parallel up to the maximum current of existing ACBs of 6300 A.
The range can be configured for installations with nominal voltages between 208V and 690V three-phase, operating at 50 or 60 Hz, making the system extremely versatile and suitable for a wide variety of application contexts.
